... Are all oil filters equal, or are some more equal? Is there a difference between the oil filter I buy at my VW dealer (for example) and oil filters such as those made by Fram, K-Marts finest, Sears best, and others? Is there a brand which makes better filters, or a brand which makes an equivalent to a VW filter for less money? The reason for this posting is that the filters you buy at VW seem to have some spring loaded mechanism in them which I have no clue to what its function is. This mechanism doesn't seem to be present in the other non-VW oil filters. Has anyone out there have some idea to what the differences are between the various oil filter types and whether it makes any difference at all? A reference to some magazine article/test would also be very appreciated. Jan.
